DEVICE FOR MOVING CARS.

SPECIFICATION forming part of Letters Patent No. 310,492, dated January 6, 1885.

Application filed November 5, 18 24. (No model.)

To aZZ whom, it may concern/.-

Be it known that I, EMORY BARNES, of Mount Pleasant, in the county of Isabella and State of Michigan, have invented new and useful Improvements in Devices for Moving Railway-Oars; and I do hereby declare that the following is a full, clear, and exact description of the invention, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and useful devices employed for overcoming the inertia of stationary bodies, and is especially designed for use in moving railway-cars in the yards or upon the track, in place of the pinch-bar and other of the ordinary appliances employed for that purpose.

The invention consists in a compound lever the expansion of which, when applied, will move the inert body, a proper point of resistance being found in a clamp adapted to embrace the head of the rail of the track.

It also consists in the peculiar construction and combination of its various parts, as more fully hereinafter described.

Figure l is a perspective view of my improvement, and Fig. 2 is a plan view of the clamp-shoe.

In the accompanying drawings, which form a part of this specification, A represents a horizontal lever, one end of which is pivoted to the lever B, the pivotal connection a forming the fulcrum for such lever B. The shorter arm of this lever B is provided with any suitable device by means of which it may be secured to or against the end of the car or body to be moved. The opposite end of the lever A is pivotally connected with the clamp O. This clamp is constructed as follows: A bar, Z2, is provided in rear of its front end with an ear, 0, which forms the point of pivotal connection with the lever A, the end of this bar projecting in front of the ear, and is designed to rest upon one of the rails of a railway-track and form a shoe to prevent, in the travel of the clamp along such rail,catcl1- ing against any joints in the track; This bar b also has projecting from each side thereof and curved downward therefrom guide-arms d, which are designed to embrace, with the bar, the top and sides of the head of the rail.

short levers or links 6, and to their free ends are pivoted similar levers or links, h, and at the rear end and on top of said levers h they are connected by a link or bar, 1', pivotally secured at each end. The ends of these levers h are case-hardened or laid in tempered steel, or thelevers themselves may be made of tempered steel, the office of this being that as a rearward pressure is brought to bear upon this clamping device the ends of such levers It will bite the sides of the head of the rail with a force increasing with the force applied in that direction, so that when the free end of the lever B is forced down toward the horizontal line it will exert its force to move the stationary or movable body at the opposite end of the device from the clamp 0. Raising the lever B releases the pressure upon the clamp, and as the/lever B draws forward the rear end of the lever A, the clamp being pivotally secured thereto, necessarily follows until the lever B is carried as high as is desired, its shorter arm resting against the car to be moved; but immediately on force being ap- A, the jaws h of the clamping device again so bite the sides of the rail that the force applied is again expended in moving the car or overcoming the inertia of the body to be moved.

hat I claim as my invention is 1. In a device for the purposes described, the clamp 0, having guides to support it upon the top of the rail, and jaws to bite either side of the head of the rail, constructed and operating substantially as described.

2. In combination with the clamp 0, constructed substantially as described, the lever A, pivotally secured at one end to such clamp, and having pivotally secured to its free end the lever B, the parts being constructed, arranged, and operating substantially as and for the purposes specified.

EMORY BARNES.
